Abstract
In general, this disclosure relates to extracorporeal fluid circuits. In some aspects, an air-release device for allowing air to be released from a liquid in extracorporeal circuitry includes an elongate chamber having a bottom region and a top region and a fluid entry port and fluid exit port at or near the bottom region. The air release device also includes a vent structure at or near the top region of the elongate chamber that includes a porous material capable of swelling when moistened such that the vent structure can inhibit liquid from escaping the air-release device during use.
